Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare read-only, idempotent, non-destructive, and closed-world behavior, so safety is covered. The description adds genuine value beyond that by disclosing that drafts are included and that results are ordered newest first, but it says nothing about pagination behavior or how the limit interacts with total result count.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

A single compact clause with no filler, and the scoping facts (drafts included, newest first) come first. It is a sentence fragment rather than a full statement, which is efficient but slightly terse for a tool description.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description carries some burden for explaining what an entry looks like, and it does not; it also omits pagination semantics. It is adequate for a simple read-only list given that annotations cover the safety profile and the schema covers both parameters, but it leaves the return shape unstated.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%: productId already points to list_products and limit already documents the 1-50 range and default of 25. The description adds no parameter-level meaning beyond the schema, so the baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The resource is named precisely (a hosted product's changelog) and the scope modifiers 'drafts included' and 'newest first' tell an agent exactly what set and ordering it returns. The verb comes from the tool name rather than the description, and it does not explicitly contrast with create/update/delete_changelog_entry or draft_changelog_from_releases, so it falls short of a 5.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no when-to-use statement, no prerequisite, and no named alternative. The only implicit cue is 'drafts included,' which hints it is the read path that surfaces unpublished entries, but an agent gets no explicit routing guidance among the many changelog siblings.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
